Kumenyekanisha imitwe irinda umuriro
Igitambaro cyo gukingira umuriro (flame-retardant headgear) gikoreshwa cyane cyane kurinda umutwe, uruhande nijosi mugihe cyo kuzimya umuriro, umuriro cyangwa ubushyuhe bwinshi. Yujuje ibyangombwa bisabwa na GA869-2010 "Igitambaro cyo Kurinda Umuriro Kurinda Abashinzwe kuzimya umuriro", kandi irashobora gutanga raporo y'ibizamini hamwe na 3C. Ikozwe mubintu byingenzi bya flame-retardant ibikoresho nka aramid. Ifite umuriro mwiza na flame retardant, kandi ntizakomeza gutwika mugihe habaye umuriro. Ubwinshi bwayo bworoshye nubwitonzi bwiza butuma ibicuruzwa byoroha kwambara, byiza kandi byiza mumikorere. Igishushanyo mbonera cya kimuntu kirashobora kurinda neza umutekano wuwambaye umutekano wumutwe wose, kandi gikoreshwa cyane mubijyanye no kurinda umuriro, ibyuma, peteroli, ninganda zikora imiti.
Ibiranga tekinike
1. Imikorere ya flame retardant: uburebure bwintambara ni 7mm, uburebure bwangiritse ni 5mm, guhora gutwika ni 0s, nta gushonga cyangwa gutonyanga.
2. Nyuma yikigereranyo cya 260 ℃ gipimo cyumuriro, igipimo cyimpinduka zingana kuruhande rwintambara nicyerekezo ni 2%, kandi hejuru yicyitegererezo nta mpinduka zigaragara nko guhindura amabara, gushonga no gutonyanga.
3. Urwego rwo kurwanya ibinini rwigitambara ni urwego rwa 3, nta bikoresho bya fordehide bigaragara, agaciro ka PH ni 6.72, imbaraga zidasanzwe ni 1213N, naho igipimo cyo guhindura ingano yo gufungura isura ni 2%.
4. Igipimo cyo gukaraba cyahinduwe ni 3,4% muburyo buhagaritse na 2,9% muburyo butambitse.
